Product Description

BL983329-2 Mini TDS Controller is designed for precise, continuous measurement of total dissolved solids in process streams within the range of 0 to 999 ppm (mg/L). Engineered for panel mounting, this industrial controller operates on a 230VAC power supply and delivers industry-standard 4-20 mA output for integration with process control systems.

The unit is equipped with both automatic and manual dosing modes. In automatic mode, a dry contact relay activates when the measured value exceeds the user-adjustable setpoint, allowing seamless dosing pump or solenoid valve control for water treatment, industrial processes, and laboratory systems.

Key technical features include an EC/TDS dosing relay (max 2A, 250 VAC/30 VDC, fuse protected), EC to TDS conversion factor of 0.5, multicolor LED status indicator, and fire-retardant, splash-resistant casing to ensure long-term durability and safe operation. Automatic temperature compensation (5–50°C, β=2%/°C) maintains accuracy, while manual calibration ensures ongoing alignment to standards.

Measurement range: 0-999 ppm (mg/L).
Accuracy: ±2% full scale.
Relay control triggered above adjustable setpoint.
Compact dimensions: 83 x 53 x 99 mm.
EC/TDS dosing relay, max 2A (fuse protected).
Adjustable over-dosing control: 5–30 minutes.
Automatic temperature compensation from 5 to 50°C.
Manual calibration via CAL trimmer.
Protective LCD cover and LED status indicator.

This controller is ideally suited for industrial water treatment, laboratory automation, chemical process monitoring, and commercial HVAC or manufacturing systems needing precise TDS management. Explore more in EnvMart's Laboratory Controllers & Mini Controllers category.
